features/shard: Add "is-directory" checks in stat/fstat
During mount, NFS directly calls stat on the root of the volume without sending a lookup on it. This was causing inode_ctx_get_block_size() to fail on /. A check is now added in [f]stat which would ensure no action is taken by shard xlator when the operation is on a directory.
